In the minds of a great many, Donald Trump is not a good man. What began with questionable comments about women and race has, for some observers, evolved into rhetoric that challenges alliances and unsettles global stability. NATO partners have at times been subjected to threats and sharp criticism, while countries such as Iran have felt the edge of his confrontational approach. The question many now ask is: who might be next?

Humanity is marked by a broad spectrum of emotional capacity, particularly when it comes to caring for others—the essential glue that binds societies together. Some individuals, often in times of conflict, demonstrate a hardened resilience that enables them to act decisively under pressure. In places like Ukraine, that resilience has been seen as vital. Leaders, too, require the ability to make difficult decisions without becoming paralysed by moral hesitation.

Yet critics argue that Trump appears to lack the balance of empathy and restraint that tempers such toughness. Where firmness is required, they see instead a disregard for nuance or compassion. He has frequently dismissed values—such as regulated speech and constrained commerce—that many European nations uphold as necessary elements of a mature, stable society. To some, this perceived rejection of shared principles has widened the divide between the United States and Europe, fuelling tension rather than unity.

Aggressive rhetoric on the global stage can provoke similarly forceful responses, energising divisions both abroad and at home. History shows that societies which nurture peace and cooperation may nonetheless find themselves vulnerable to more militant adversaries. The ongoing war in Ukraine is a stark example. Elsewhere, including in Iran, populations often hold more liberal and compassionate views than the governments that rule them, creating internal dissonance as well as external friction.

When such an approach to leadership is paired with the immense economic and military power of the United States, its global impact is magnified. Trump’s reliance on bluster, brinkmanship, and at times outright confrontation has prompted concern about the long-term consequences of this style of diplomacy. For many, it raises doubts about the logic of pursuing peace through intimidation, a contradiction that undermines the very concept of stability.

At the same time, divisions within Western politics can weaken collective resilience, potentially benefiting rival powers. China, for instance, may adopt a patient strategy, waiting for geopolitical advantages to emerge rather than risking direct military confrontation, particularly in sensitive areas such as Taiwan.

Trump’s unpredictability is often portrayed as both a personal trait and a deliberate tactic. While some see this as a strategic asset, others view it as a destabilising force. Concerns have also been raised about his age and fitness for office, with critics pointing to moments of inconsistency or confusion. Should his tenure end prematurely, attention would inevitably turn to Vice-President J.D. Vance.

Vance himself divides opinion. Seen by some as ideologically driven and uncompromising, he raises questions about what direction US leadership might take in such circumstances. However, the constitutional framework of checks and balances remains a significant counterweight. Increasing unease among Republican legislators suggests that internal constraints on executive behaviour may yet play a decisive role.
